Title: Intermediates for synthesis of arachidonic acid
IPC: C07C17/26
Filed: 1959-12-10
Abstract: The invention comprises 1-chloro-nonadecatetrayne-(4,7,10,13) and the corresponding tetraene, and their manufacture by condensing decadiyne (1,4) with 1 - bromo - 9 - chloro - nonadiyne-(2,5) in a Grignard reaction, and if desired, partially hydrogenating the tetrayne to the tetraene, e.g. with about 4 molar proportions of hydrogen and a Pd/Pb/CaCO3 catalyst containing 5% Pd. The Grignard reaction is preferably effected in the presence of a cuprous salt. The 1-chloro-nonadecatetraene-(4,7,10,13) may be carboxylated, e.g. with Mg and CO2, to arachidonic acid. Decadiyne-(1,4) is prepared by condensing heptyne-1 with propargyl halide in a Grignard reagent, e.g. in ether in the presence of a cuprous salt. Methyl arachidonate is prepared by reacting arachidonic acid, obtained as above, with diazomethane, and is hydrogenated to methyl arachidate. Nonadecyl chloride is obtained by reduction of the tetraynyl chloride, and is converted to the cyanide and so to arachidic acid. Specification 883,482 is referred to.
Patent ES-259601-A1 (ES)
Title: Stabilization of lubricants
Filed: 1960-07-12
Abstract: A lubricant is stabilized by incorporating therein a stabilizing concentration, e.g. 0,01% to 5% of 4,41-di-(sec-alkylamino)-diphenyl methane, N,N,N1,N1-tetra-(sec-alkyl)-4,41-diamino diphenyl methane, or N,N,N1,N1-tetraethyl-4,41-diamino diphenyl methane. Examples of the inhibitor are 4,41-di-(isopropylamino) diphenyl methane, 4,41-di(sec-butylamino)diphenyl methane, N,N,N1,N1,-tetra-(sec-butyl) 4,41-diamino diphenyl methane, N,N,N1,N1tetra-(isopropyl)4,41-diamino diphenyl methane, and N,N,N1,N1,-tetra-ethyl-4,41-diaminodiphenyl methane, also compounds, as above, in which the phenyl groups are substituted in the 2-position. Preferably the alkyl substituents are the same and contain from 3 to 12 carbon atoms each in the di-alkyl substituted compounds, and from 2 to 12 carbon atoms each in the tetra-alkyl substituted compounds. The invention which is particularly applicable to stabilizing synthetic lubricants, e.g. aliphatic esters, polyalkylene oxides, silicones, esters of phosphoric and silicic acids, and highly fluorinated hydrocarbons, may also be applied to petroleum base lubricants, petroleum base greases, and to synthetic greases. The synthetic greases are made by compositing metallic soaps, e.g. lithium stearate, calcium stearate and aluminium naphthenate, with the synthetic lubricating oils described above. The grease may also contain thickening agents such as silica, carbon black, metal oxides, phthalocyanines, polyacrylates, talc, bentonite, organo treated clays, alkyl ureas, aryl ureas, p-tolyl and p-chlorophenyl urea derivatives of bitolylendiisocyanate, p teridines and N-n-octadecylterephthalomate. The amino diphenyl-methane additive may be prepared as a solution in a hydrocarbon solvent and may be used with other additives such as a metal deactivator, dye, viscosity index improver, pour-point depressant, anti-foaming additive, lubricity and extreme pressure additive, or a detergent.
Patent ES-293102-A1 (ES)
Title: Data control of carrier injection in sideband transmission systems
IPC: H04B1/68
Filed: 1963-11-02
Abstract: In a single sideband transmission system for binary data signals in which a small amount of carrier signal is transmitted to ensure correct operation of an associated receiver and in which when the data signal comprises a predominance of binary " ones " or binary " zeros " sufficient D.C. voltage is present in the signal to unbalance the balanced conductor 12 to provide the carrier signal, means are provided for adding a D.C. voltage to the modulating signal to unbalance the modulator when the data signal alternates too frequently between " one " and " zero " to provide the required unbalancing D.C. voltage. The data signals on line 14 are applied directly via adder circuit 16 to the balanced modulator 12 and also to an integrating circuit 18 which provides an output corresponding to the difference between the number of " ones " and " zeros " in the signal. This output voltage is applied to a decision circuit 28, including two differently biased trigger circuits 24, 26 and an inverter circuit 34, which provides no output to adder circuit 16 when there is a predominance of " ones " or " zeros " in the data signal and a D.C. signal which is added to the data signal when the value of the difference signal falls between the two bias voltages applied to the triggers.

Patent ES-311884-A1 (ES)
Title: Three-phase four-wire induction meter
IPC: G01R11/40
Filed: 1965-04-14
Abstract: Each E-shaped voltage magnet of a three phase induction meter has a counterpole 6 linked by a ferromagnetic bridge member 8 to the corresponding U-shaped current magnet 3. As shown non-magnetic packing 9, 10 - the thickness of which may be varied in assembly - provides for reluctance adjustment. This may however be omitted and the bridge either (a) joined directly to both the counterpole 6 and the current magnet 3 or (b) joined directly to one and spaced from the other - in which case the space may be variable by the use of a non-magnetic adjusting screw. The consequent shunting of the magnetic field between the voltage and current poles of each drive system reduces interaction between the drive systems of adjacent phases, and so compensates for rotary field error. By making the packing 9, 10 of a substance whose reluctance is temperature dependent, the meter may be temperature compensated.

Abstract: A fuel handling arrangement for transferring spent elements from the core 12 of a gas-cooled heavy water moderated reactor to a pond 124 and for introducing new elements comprises a facility A disposed in a space 18 in the pressure vessel 10 above a shielding slab 20. The facility A includes a beam 22 rotatable about the axis of the reactor and supporting a carriage carrying a grab, whereby the grab may be aligned with a selected servicing channel 14 and transfer fuel elements from the core 12 into a thimble (not shown) disposed in a pick-up pit 90. The drive motors for the beam, carriage and grab are contained in a dome 66. An ancillary enclosure 92 contains a lock 100 bounded at one end by valves 96, 98 and at the other end by a valve 104, this lock being in alignment with the pit 90 whereby a grab controlled by a winch 102 may raise the thimble through guide sleeves 95, 94 into the lock, the valve 104 being closed. The thimble is retained in the lock 100 by a latch so that the grab may be disconnected and moved laterally out of alignment with the lock. The valves 96, 98 are closed, the gas pressure in lock 100 is reduced to atmospheric, valve 104 is opened and a grab controlled by a winch 106 is lowered through a guide sleeve 110 to engage the thimble. The winch 106 is supported by a carriage on rails 108 so that the thimble may be lowered through a discharge channel 112 into a receptacle carried by a carriage 118 running on rails 116. Undamaged fuel elements are transferred one-by-one from the carriage 118 by means of a winch 130 through a passage 126 into a duct 133. The duct 133 is carried by an arm movable about a vertical axis whereby the duct may be brought beneath a grab carried by a travelling bridge 132 and the fuel element taken to a selected part of the pond 124. Damaged elements are placed in a flask 140 by means of a winch 135. New fuel elements are introduced into the receptacle carried by carriage 118 by means of a winch 142 situated above a fuel element store 144.

Patent ES-376277-A1 (ES)
Title: Ethylene dichloride purification by plural stage distillation
IPC: C07C17/38
Filed: 1970-02-06
Abstract: A purification separation of the residual ethylene dichloride from the higher boiling chlorinated materials found in the bottoms fraction of a heavy ends column in a vinyl chloride monomer plant is carried out by passing the bottoms fraction to a vaporization zone maintained at about 112 DEG C. The ethylene dichloride rich overhead from the vaporization zone is then passed to a fractionation column maintained between about 87 DEG and about 117 DEG C. The overhead from the fractionation column contains ethylene dichloride essentially free of higher boiling chlorinated materials and tars. This ethylene dichloride purified of "tars and carbon" and containing principally only 1,1,2-trichloroethane impurity, can be returned to the conventional VCM process distillation purification system which then separates this stream to yield high-quality ethylene dichloride for use as feed to an ethylene dichloride pyrolysis unit or for production of saleable ethylene dichloride product of high commercial quality.
